Question 284176
They have to be even numbers.
If they were both odd, the product would be odd.
If one were odd and one even, the sum would be odd.
--------------------------------
They have to be multiples of 10.
The 2 LS digits are 00.  If they're not multiples of 10, then one of the numbers is 25, but it's already been determined that both number are even.
That makes the problem:
what two numbers added together that equals 7 but when multiplied it equals 6?
That factors of 6 are 1 & 6, or 2 & 3
1 + 6 = 7
--> 10 & 60
